As early as 1934/35, General Heinz Guderian envisioned two basic types of armor to act as the lead elements of the future German Panzer Divisions. The first vehicle was to be armed with an anti-tank gun and two machine guns while the second one was to be a support vehicle, armed with a larger caliber gun.

Developed by the Quartermaster Corps, the jeep and other motor transport vehicles were transferred to the Ordnance Department in August 1942. Despite its lightweight, the jeep could perform a variety of functions, including towing a 37mm antitank gun over a 7% grade.

The Fiat SPA TL-37 artillery tractor was an innovative design produced for the Italian army during WWII. One of the main characteristics of the design was the system of all-wheel steering. All-wheel steering reduced the length of the vehicle and allowed for a much tighter turning radius.

During the early to mid-stages of the Second World War, the Stuka (short for "sturzkampfflugzeug" or dive-bomber) struck terror in the hearts and minds of soldiers and civilians alike. The Stuka was a rugged machine, designed to swoop down and destroy its target using 500-lb bombs or tear into them using 37mm flak guns mounted underneath the wings.

Early in June 1944, Army commanders expressed a need for a new breed of tank that could mount either a 90mm or 105mm main gun. This request was approved by the Army Staff soon thereafter even though trials of the new T26E1 had already begun back at Fort Knox earlier that year.

The AAVP7A1 is an armored assault amphibious full-tracked landing vehicle. The vehicle carries troops in water operations from ship to shore, through rough water and surf zone. It also carries troops to inland objectives after ashore.

Nicknamed the "Butcher Bird," the Fw 190 was Germany's best air-to-ground fighter. Faster and more agile than the British Spitfire, it dominated the skies over Europe as a fighter and was the Luftwaffe's most important ground-attack aircraft. Controlled by the skilled hands of aces like Oberleutnant Otto Kittel, the FW-190 gained the reputation of being one of the greatest fighters of all time.

The F6F embodied the early lessons learned by users of Grumman's previous fleet-defense fighter, the Wildcat. In June 1941, Grumman lowered the wing center section to enable the undercarriage to be wider splayed, fitting more armor-plating around the cockpit to protect the pilot while also increasing the fighter's ammunition capacity.

The Grumman F8F Bearcat (affectionately called "Bear") was an American single-engine naval fighter aircraft of the 1940s. It went on to serve into the mid-20th Century in the United States Navy and other air forces, and would be the company's final piston engined fighter aircraft.
